FAQ

An HMBP (Hazardous Materials Business Plan) is a regulatory requirement in California for facilities that handle hazardous materials. It ensures safety, emergency preparedness, and compliance with CalEPA regulations. Without one, businesses risk heavy fines, penalties, or even operational shutdowns.

If your facility stores, uses, or handles hazardous materials in quantities that meet or exceed state thresholds (55 gallons for liquids, 500 lbs for solids, and 200 ft³ for compressed gases), you must file an HMBP with the California Environmental Reporting System (CERS). Our team can review your operations and confirm whether your business qualifies.

Failure to comply can result in costly fines, CUPA (Certified Unified Program Agency) rejections, or regulatory enforcement actions. CalHaz Pro ensures timely and accurate submissions to keep you audit-ready and worry-free.

Your HMBP must be reviewed and updated annually, or whenever there are significant changes in your facility (e.g., new hazardous materials, layout changes, or updated emergency response procedures). We offer continuous management services to keep you compliant year-round.
